Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Windows 10 Release Date Announced

Windows 10 Home will be $119, Pro $199.

Microsoft: Windows 10 Home costs $119, Pro costs $199



Which is good news actually, because Windows 8.1 is loads cheaper than previous versions (retail licensing at Windows 7 OEM prices). And it sort of puts a huge hole in the Windows subscription theory.
